Description

Technical Field

[0001] The utility model relates to the technical field of pile sinking guide frames, in particular to a counter-pressure bottom-seating pile sinking guide frame. Background Art

[0002] The jacket foundation is a major form of offshore wind turbine foundation, mainly composed of four foundation piles and a jacket. The four legs of the jacket are inserted underwater into four steel pipe piles, and finally grouting is performed in the annular space formed between the inner wall of the steel pipe pile and the jacket legs to connect and fix them, forming a four-pile jacket wind turbine foundation structure. In order to ensure that the jacket tip can be smoothly inserted into the steel pipe pile, the steel pipe pile sinking accuracy needs to be strictly controlled. One of the main measures to control the verticality of the steel pipe pile is to control the horizontality of the pile sinking guide frame.

[0003] Traditional pile guide frames mainly include reverse-pull pile guide frames, auxiliary piles, anti-sinking plate combined bearing pile guide frames, and suction bucket pile guide frames. The reverse-pull pile guide frame has the characteristics of high leveling accuracy, but the platform erection and leveling time is long, and it is not suitable for deep water areas; the auxiliary pile, anti-sinking plate combined bearing pile guide frame has the characteristics of fast platform erection and mature technology, but its platform level control is more difficult, usually requiring multiple lifting and lowering to adjust the level; the suction bucket pile guide frame has the characteristics of high leveling accuracy, but its sinking process is more cumbersome and takes a long time. Compared with other centralized pile guide frames, the reverse pressure pile guide frame has the characteristics of high leveling accuracy and short leveling time. Utility Model Content

[0023] Working principle: The crane ship lifts the counter-pressure bottom-sinking pile guide frame to the machine position. According to the measurement and positioning system, the center position and torsion angle of the platform are observed in real time. The surveyor directs the ship to shift to ensure that the deviation between the center of the platform and the center of the designed machine position is less than one meter. After the platform anti-sinking plate is placed on the mud surface and the hook is not under force, the surveyor hooks up to the guide frame body 4 through the rigging to measure the horizontality of the platform; if the horizontality is less than 3 / 1000, it will start to unhook. If the horizontality is greater than 3 / 1000, it is necessary to weld a stopper on the auxiliary pile 3 on the higher side of the guide frame body 4, and press the high point downward through the stopper and the jack to complete the horizontal adjustment. Lift the vibrating hammer to clamp the auxiliary pile 3. After the hook is lifted about 30 cm, pull out the pin of the auxiliary pile 3, lower the auxiliary pile 3, and start sinking the pile with minimum energy. After the diagonal sinking of the auxiliary pile 3 is completed, measure the horizontality of the platform. After the crane lifts the foundation pile 1 and turns over the foundation pile 1, the foundation pile 1 is placed in the dragon mouth of the guide frame body 4, and the foundation pile 1 is slowly lowered. The foundation pile 1 is inserted into the sleeve using the dragon mouth of the top platform and the inclined surface of the sleeve top for guidance; the posture of the foundation pile 1 needs to be measured during the lowering process, and it can be adjusted by the jack; repeat the above operation to complete the insertion of four foundation piles 1. After the insertion of the piles is completed, the pile driver and the hydraulic hammer are lifted to start the first hammering and sinking of the piles. When the pile top is about two meters above the sea level, the hammering is stopped, and the hydraulic hammer is lifted to start the first pile sinking of the second foundation pile 1. After all four foundation piles 1 have completed the first pile sinking, the big arm is adjusted to insert the pile driver, and the four foundation piles 1 are sunk to the designed elevation in turn. After the foundation pile 1 is sunk, the vibrating hammer is lifted to pull out the four auxiliary piles 3 in turn and fix them on the platform with pins, and the guide frame body 4 is lifted to move to the next machine position.
